C++指针之数组冒泡排序

bubbleSort.cpp

#include 
using namespace std;

void bubbleSort(int * arr, int len)
{
	for (int i=0; i< len-1; i++)
	{
		for (int j=0; j
			if (*(arr+j) > *(arr+j+1))
			{
				int temp = *(arr+j);
				*(arr+j) = *(arr+j+1);
				*(arr+j+1) = temp;
			}
		}
	}
}

void bubbleSort02(int * arr, int len)
{
	for (int i=0; i< len-1; i++)
	{
		for (int j=0; j
			if (arr[j] > arr[j+1])
			{
				int temp = arr[j];
				arr[j] = arr[j+1];
				arr[j+1] = temp;
			}

	}
}

int main()
{
	int arr[10] = {4,3,6,9,1,2,10,8,7,5};
	int len = sizeof(arr)/sizeof(arr[0]);

	for (int i=0; i
